How to choose canned tomatoes

When evaluating canned tomatoes, search for those that are bright red and emit a fragrance akin to fresh tomatoes. They should be preserved in their own juice with few additives. Prefer options labeled as organic or non-GMO for optimal quality and health benefits.

Avoid canned tomatoes that have a metallic taste or a mushy texture, as these characteristics can diminish their culinary value. The finest canned tomatoes should feature firm, intact tomatoes that taste vibrant and fresh.

A cool, dry pantry is perfect for storing unopened canned tomatoes. Once opened, place them in an airtight container and refrigerate. This will help them stay fresh for up to five days.

Storing tomatoes in the original can after opening can lead to a metallic taste. Transfer them to a glass or plastic container to maintain their flavor. Ensure the lid is tightly closed to prevent spoilage. Always use clean utensils to avoid introducing bacteria.

To enhance the flavor of stored canned tomatoes, add a pinch of salt or a drizzle of olive oil when transferring them to the container.

Canned tomatoes can last for 1-2 years when stored in a cool, dark place. Once opened, they should be refrigerated and used within 3-4 days. Transfer them to an airtight container after opening to maintain their freshness.
